Present embodiments provide a kind of flat segmentation sandblasting coating support method for arranging, comprising the following steps:
Early-stage preparations: prepare 3,50 tons of support devices 2 of a certain number of 50 tons of height-adjustable auxiliary support apparatus and pad
Wood 5.
It is flat to be segmented 1 into the arrangement (corresponding step a ') before sand canopy:
1) support device 2 should be evenly arranged and reserve into truck position around 1 center of gravity 200 of flat segmentation, and should be placed in strong
11 position of frame structure；
2) chock 5 should be placed when flat segmentation 1 is stacked, support device 2 must not be contacted directly with flat segmentation 1, and chock 5 is high
Degree control should ensure that 5 upper surface of chock level between 100-300mm；
3) Force Calculation is carried out to arrangement, calculates the stress condition that content includes: support device 2；Ground bearing pressure
It calculates；
Specifically, according to ∑ M=M1+∑M2；∑ S=S × N；F2=∑ M/ ∑ S, can obtain
In formula: ∑ M indicates that the total weight of ground loading, unit are ton (T)；∑ S indicates that support device 2 is always contacted with ground
Area, unit are square metre (m2)；M1Indicate that the weight of flat segmentation 1, unit are ton (T)；∑M2Indicate the total of support device 2
Weight, unit are ton (T)；S indicates the base area of support device 2, and unit is square metre (m2)；The number of N expression support device 2
Amount, unit is a.
4) arrangement should meet the load-bearing requirements on practical stacking place ground.
Arrangement when flat segmentation 1 is transported to sand canopy:
1) the selection quantity of support device 2 must consider product sand weight of the flat segmentation 1 in sandblasting procedures comprehensively.In product sand
In the case that weight can not be estimated clearly, support device 2 takes 0.6 safety coefficient.2 quantity of support device
(corresponding step a)
2) according to the usage quantity of support device 2, be arranged in flat segmentation 1 close up it is strong at mouth region domain 100
11 lower section of frame structure；(corresponding step b)
3) support device 2 is carried out padded using chock 5, and support must not be contacted directly with flat segmentation 1, and chock 5 is highly controlled
System must assure that 5 upper surface of chock level between 100-300mm.Chock 5 must be arranged in 2 roof center position of support device
It sets and outer plate edge that chock 5 long side must be adjacent is parallel；
4) arrange that 4 height-adjustable auxiliary support apparatus 3 are used as safety supports position in flat segmentation 1 center of gravity, 200 surrounding,
The length and width spacing of each safety supports position should control between 1/2La~2/3La, 1/2Lb~2/3Lb, and be greater than this flat point
4 width of transport vehicle selected when transporting of section 1.Roof supporting is contacted using chock 5 with ship hull plate.Safety supports must carry out cabin
Screwed before interior and interior bottom sandblasting operation, prevent it is flat segmentation 1 200 region of center of gravity because product sand weight it is excessive caused by it is flat segmentation 1
It deforms and topples over.Safety supports position is unclamped after removing to interior bottom and cabin inner product sand, is allowed to not influence the sandblasting and painting of outside plate
Dress.(corresponding step c)
5) because flat segmentation 1 is longer in the canopy period, to prevent from leading to deformation of hanging down in flat segmentation 1 because stacking excessive cycle,
After the removal of smooth transport vehicle 4 is placed in flat segmentation 1, close up a mouthful strong frame at flat 1 disengaging vehicle direction both ends of segmentation with fork truck
A height-adjustable auxiliary support apparatus 3 is respectively filled at structure 11 and is held out against, and Auxiliary support is used as.
It is used it should be noted that height-adjustable auxiliary support apparatus 3 is supported not as stress, calculates support device 2
Quantity not comprising auxiliary support apparatus 3 when usage quantity.
Checkout procedure:
1) quantity of support device 2 must meet carrying demand.
2) support device 2 is mainly arranged in the position of strong frame structure 11.
3) support device 2 must intact no breakage.
It 4) must be steady with ground face contact when support device 2 is put.
5) chock that transport vehicle 4 goes out on the supporting surface of vehicle rear support device must contact close tight with segmentation.
Note that the above is only a better embodiment of the present invention and the applied technical principle.It will be appreciated by those skilled in the art that
The present invention is not limited to specific embodiments mentioned here, be able to carry out for a person skilled in the art it is various it is apparent variation,
